How To Inspect Heavy-duty Connectors

Visual Inspection Standards for heavy duty cable connectors

heavy power connector must be free of deformation, bending, oxidation, or stains. On the conductive parts of heavy duty wire connectors pins or pin sockets. Use a vernier caliper and micrometer to verify that the length and outer diameter of wire connector heavy duty fall within the specified range.

Functional Inspection
 
Use a multimeter to check whether the resistance value of the internal conductive terminals of heavy duty electric cable connectors is within the standard range. Place the pins into a solder pot at 270±5℃ for resistance soldering. Remove from the solder pot and test functionality after 3 hours. If results match pre-test conditions, no heat loss due to connection occurs.

Precautions for heavy duty electric cable connectors Functional Inspection:

1. Wear protective gloves when inspecting heavy duty 12v connectors.

2. Solderability and solder joint heat resistance should be tested on 10 pieces per batch.
